Severity:	normal
Title:	jabberd 1.x: Denial of Service vulnerability
Date:	09/23/2004
Bugs:	#64741
ID:	200409-31

Synopsis

The jabberd server was found to be vulnerable to a remote Denial of Service attack.

Background

Jabber is a set of streaming XML protocols enabling message, presence, and other structured information exchange between two hosts. jabberd is the original implementation of the Jabber protocol server.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-im/jabberd	<= 1.4.3-r3	>= 1.4.3-r4	All supported architectures

Description

Jose Antonio Calvo found a defect in routines handling XML parsing of incoming data. jabberd 1.x may crash upon reception of invalid data on any socket connection on which XML is parsed.

Impact

A remote attacker may send a specific sequence of bytes to an open socket to crash the jabberd server, resulting in a Denial of Service.

Workaround

There is no known workaround at this time.

Resolution

All jabberd users should upgrade to the latest version:

    # emerge sync
    
    # emerge -pv ">=net-im/jabberd-1.4.3-r4"
    # emerge ">=net-im/jabberd-1.4.3-r4"
